You are using a recovery catalog to maintain Recovery Manager (RMAN) backup information for yourproduction database. You have registered your production database and are performing regular backups.Because of a new requirement you have added a few new tablespaces to your production database and youwant them to be included in backups.Identify two options for completing this task. （）(Choose two.)

A. Reregistering the target database in recovery catalog

B. Transporting the new tablespaces to the recovery catalog database

C. Syncronizing the recovery catalog with the target database control file

D. Performing a fresh backup of the target database to include the new data files in the catalog database

You are using Recovery Manager (RMAN) for backup and recovery operations with a recovery catalog. You have been taken database backups every evening. On November 15, 2007, at 11:30 AM, you were informed that the USER_DATA tablespace was accidentally dropped.On investigation, you found that the tablespace existed until 11:00 AM, and important transactions were done after that. So you decided to perform incomplete recovery until 11:00 AM. All the archive logs needed to perform recovery are intact. In NOMOUNT state you restored the control file that has information about the USER_DATA tablespace from the latest backup. Then you mounted the database. Identify the next set of commands that are required to accomplish the task？ （）

A. A

D. D

In Recovery Manager (RMAN), you are taking image copies of the data files of your production database and rolling them forward at regular intervals. You attempt to restart your database. After a regular maintenance task, you realize that one of the data files that belongs to the USERS tablespace is damaged and you need to recover the data file by using the image copy. Because a media failure caused the data file to be damaged, you want to place the d ata file in a different location while restoring the file.Which option must you consider for this task？（）

A. using only the RMAN SWITCH command to set the new location for the data file

B. placing the database in the MOUNT state for the restore and recovery operations.

C. using an RMAN RUN block with the SET NEWNAME and then the SWITCH command.

D. configuring two channels: one for the restore operation and the other for the recovery operation

You want to create the Recovery Manager (RMAN) Virtual Private Catalog (VPC) to maintain a separation of responsibilities along with a consolidation of RMAN repository.Which condition must be met before you create the VPC？（）

A. A base catalog exists

B. The recovery catalog is empty

C. The base recovery catalog must be dropped

D. A target database is registered in the recovery catalog

A. You can use RMAN stored scripts

B. Recovery is faster if data is stored in catalog in addition to the control file

C. You can store backup information of all registered databases in one place

D. Database backups are automatically deleted when they are older than the specified time period

A. You must configure block change tracking file

B. You must have first level 1 backups for RMAN to restore blocks

C. You must ensure that the SALES database is mounted or open

D. You must have full or level 0 backups for RMAN to restore blocks

E. You must take the tools01.dbf data file offline before you start a block media recovery

You are using recovery Manager (RMAN) with a recovery catalog to backup up your production database. The backups and the archived redo log files are copied to a tape drive on a daily basis. The database was open and transactions were recorded in the redo logs. Because of fire in the building you lost your servers having the production database and the recovery catalog database.The archive log files generated after the last backup are intact on one of the remote locations.While performing a disaster recovery of the production database what is the next step that you must perform after restoring the data files and applying archived redo logs？（）

A. Open the database in NORMAL mode

B. Open the database in read-only mode

C. Open the database in RESTRICTED mode

D. Open the database with the RESETLOGS option

A. You must configure block change tracking file

B. You must have first level 1 backups for RMAN to restore blocks

C. You must ensure that the SALES database is mounted or open

D. You must have full or level 0 backups for RMAN to restore blocks

E. You must take the tools01.dbf data file offline before you start a block media recovery

A. New channels for restore and recovery tasks

B. New name for the data files of the tablespace

C. Auxiliary name for the data files of the tablespace

D. Auxiliary destinations for an auxiliary set of data files

You are using Recovery Manager (RMAN) with a recovery catalog to back up your production database. Thebackups and the archived redo log files are copied to a tape drive on a daily basis.Because of media failure,you lost your production database completely along with the recovery catalog database.You want to recover the target database and make it functional. You consider performing the following steps to accomplish the task:1) Restore an autobackup of the server parameter file.2) Restore the control file3) Start the target database instance4) Mount the database5) Restore the data files6) Open the database with RESETLOGS option7) Recover the data files8) Set DBID for the target databaseWhich option illustrates the correct sequence that you must use？（）
